Describe the bug

In the connect wizard, I should only be able to connect when "Server" and "Token" have valid values.

Che version

7.109@latest

Steps to reproduce

1. EXEC: in Gateway: hit "Connect to Dev Spaces"
2. ASSERT: you get the server wizard page
3. ASSERT: Server and Token are selected from your kubeconfig (picked from current-context)
4. EXEC: delete the token

5. EXEC: try to hit "Check connection.."

Result:
"Check connection.."-button is enabled, you can hit it. Connection then fails of course because you didn't provide a token.

Expected behavior

Server and Token are required, "Check connection..."-button should only be enabled once you have valid values in both.
